?subsp. sparsiprocessum (Varma and Dangwal, 1964, p.64, pl.1, fig.7) Eisenack and Kjellström, 1972, p.453. Holotype: Varma and Dangwal, 1964, pl.1, fig.7. Originally Hystrichosphaeridium heteracanthum subsp. sparsiprocessum, subsequently Heterosphaeridium heteracanthum subsp. sparsiprocessum, thirdly Heterosphaeridium? heteracanthum subsp. sparsiprocessum, fourthly (and now) Heterosphaeridium heteracanthum? subsp. sparsiprocessum. Questionable assignment: Fauconnier and Begouën in Fauconnier and Masure (2004, p.270) as a problematic taxon, suggesting that the name be restricted to the holotype. Age: Eocene–Oligocene.
Parent: Heterosphaeridium heteracanthum
